Calibration Column
Calibration Columns are precision-engineered instruments designed for the accurate calibration and verification of chemical injection systems. These columns are essential components of chemical injection skids, ensuring precise dosing and reliable operation of the injection process. Built with high-quality materials and advanced engineering, our calibration columns provide superior performance, durability, and ease of use in a wide range of industrial applications.
The Calibration Column from IPS Automation is a precision measuring accessory used to
verify and calibrate the flow rate of chemical dosing pumps and metering pumps. It is typically
installed on the suction side of the pump and provides a clear, graduated chamber that allows
operators to measure the actual volume of liquid drawn by the pump over a fixed time period.
This helps confirm whether the pump is delivering the required dosing rate accurately.
Calibration columns are widely used in chemical dosing systems where accurate injection of
treatment chemicals, additives, disinfectants, corrosion inhibitors, pH adjusters, or process
fluids is critical. During operation, the column is filled with the dosing liquid, isolated from the
storage tank, and the pump draws fluid from the column. The level drop on the graduated scale
is then used to calculate or verify the actual pump output. This makes calibration columns a
simple, reliable, and cost-effective tool for maintaining dosing accuracy in manufacturing and
process applications.

Accurate Pump Flow Verification
Calibration columns provide a direct visual method to verify the actual flow rate of dosing pumps under real operating conditions, helping ensure that the pump output matches the required dosing rate.
Cost-Effective Calibration Method
The simple graduated tube design provides an economical way to check metering pump performance without complex instrumentation or advanced flow measurement devices.
Easy Visual Monitoring
Large transparent measuring tube and dual-scale markings improve readability and operator convenience.
Flexible Material Options
Calibration columns can be manufactured using PVC, borosilicate glass, PP, PVDF, SS316L, and other compatible materials to suit different chemicals, temperatures, and operating environments.
Helps Identify Pump Issues
Regular calibration can help detect problems such as worn check valves, blockages, leaks, air entrainment, or reduced pump performance before they lead to process failures.
Improved Chemical Dosing Accuracy
By confirming pump delivery volume, calibration columns help prevent under-dosing and over dosing of chemicals in water treatment, chemical processing, pharmaceutical, food, and manufacturing applications.
Simple Installation and Maintenance
Vertical installation on the dosing pump suction line, along with isolation valves and venting arrangement, makes the calibration column easy to operate, inspect, clean, and maintain.
Supports Process Consistency
Accurate dosing improves process control, product quality, chemical treatment efficiency, and batch-to-batch consistency in manufacturing and process plants.
